Reflections on the immaterial value of using rematerial means to preserve material culture from a museum perspective
Museums are the cultural calling cards and living rooms of cities, and museum-going has become a way of life for people. With the onset of digitalisation, all aspects of the museum sector have begun to incorporate digital technology, opening up a new kind of museum experience.
While traditional museum exhibitions are generally exhibit-based, the application of digital technology in museum displays can enable museums to break through the constraints of time and space, using a variety of technologies to give artefacts vividness and interactivity, allowing visitors to have a more intuitive and richer visual experience, enhancing their sense of cultural experience while enabling a greater spread of history and culture.
As far as I know there are four core key technologies that can help us realise digitisation:
❖ Centimetre-level spatial computing
All-weather and all-scene: centimetre-level positioning and fixed posture within one degree (6DOF) support high-precision AR guidance, POI holographic signage, digital large screen and other calculations.
❖ High precision 3D recognition
High precision: millimeter-level 3D recognition of the surrounding environment and world, support for 3D landmarks (bronze bull on the Bund, Chen Yi statue, etc.) recognition, support for cultural relics, mural storytelling, etc.
❖ Highly realistic rendering
High realism: high realism fusion of digital content with the real world, realistic virtual and realistic occlusion, consistent light and shadow of virtual objects in the real world.
❖ Large-scale 3D map construction
Multi-source map acquisition and processing: automated map generation pipeline construction, support for satellite map building, large area rapid coverage capability, support for panoramic + laser map building, support for high precision positioning, support for map crowdsourcing.
In the future, emerging technologies will continue to be an important way to bring "cultural relics" to life in museums, with virtual reality, 3D panoramic views, AR and other technical means becoming more and more sophisticated, bringing more immersive and interactive experiences to the viewer. Only through the effective integration of online and offline museums can museums maintain their unique charm in an era of technological innovation, in order to meet the growing aesthetic and cultural needs of audiences.
